I'd like to hear from someone who has successfully shot a projected piece of film burning up (as in when the film gets stuck and the frame burns up and melts [the end of the Nine Inch Nails "Closer" video is a great example)

How did you do this? We have a bit of 35mm workprint that was shot specifically to burn up and I'd like to know what to shoot on and how to set it up.

Thanks!

John Pytlak gave this answer in 'another' forum:

"If you are actually photographing the movie on screen as viewed by the audience, you will need to sync your camera to the shutter in the projector to avoid any flicker or shutter bars.

To get the burned frame, just quickly cut the print film (2383, 2395) between the projector gate and the intermittent pulldown sprocket with scissors --- the film will stop instantly in the gate while the frame is stationary on the screen, which will then char and blister as it sits in the intense light beam of the projector. Any xenon lamp over 2000 watts should be enough to burn a frame stopped in the gate. Have the projectionist be ready to close the dowser to avoid too much smoke or damaging the projector lens, and then turn off the projector to avoid a film pileup above the gate.

For a bit less contrast in the on-screen image, you might consider using Kodak VISION Color Teleprint Film 2395 as your sacrificial print.

Base your exposure on the light level of the print on the screen. Standard screen luminance is 16 footlamberts, but some theatres and screening rooms have enough power to spare to give you a higher light level."
